Panduit FX23RSNSNSNM4.5 QuickNet OM3 SC Duplex Fiber

Panduit FX23RSNSNSNM4.5 QuickNet Pre-Terminated Fiber Assembly

The Panduit FX23RSNSNSNM4.5 is a 2-fiber OM3 multimode pre-terminated fiber optic assembly with SC duplex connectors on both ends, designed for high-speed 10GbE and 40GbE backbone applications in enterprise data centers, telecommunications rooms, and entrance facilities. Part of Panduit's QuickNet system, this assembly eliminates field termination labor and associated failure points by delivering factory-terminated, factory-tested connectivity that can be pulled and plugged in minutes. The OM3 50/125µm laser-optimized multimode fiber supports 300-meter reach at 10 Gigabit Ethernet and 100-meter reach at 40/100 Gigabit Ethernet, making it the workhorse choice for horizontal and short-reach vertical fiber distribution in structured cabling environments where you need headroom beyond OM2 but don't yet justify the cost premium of OM4 or OM5.

Key Features

• OM3 50/125µm laser-optimized multimode fiber certified for 10GBASE-SR (300m) and 40GBASE-SR4 (100m) applications
• Factory-terminated SC duplex connectors with Physical Contact (PC) polish for insertion loss ≤0.5 dB and return loss ≥20 dB per TIA-568.3-D
• OFNR (Optical Fiber Nonconductive Riser) jacket rated for vertical cable runs between floors in non-plenum spaces per NEC Article 770
• QuickNet pre-terminated design eliminates splice trays, epoxy curing, polishing, and field testing — reducing install time by up to 80% versus fusion splicing
• 2-fiber configuration supports simplex transceiver pairs (1000BASE-SX, 10GBASE-SR) or bidirectional single-strand applications
• Aqua-colored 3mm cable jacket for instant visual identification as OM3 per TIA-598-D color coding standard
• Complies with TIA-568.3-D, ISO/IEC 11801, and ANSI/TIA-942-B data center infrastructure standards
• Minimum order quantity: 10 units (facilitates bulk deployment in multi-rack or floor-to-floor distribution projects)

Pre-terminated fiber assemblies like the FX23RSNSNSNM4.5 solve the single biggest source of fiber installation failure: inconsistent field termination quality. Every connector on this assembly is machine-polished and insertion-loss tested at the factory, then individually serialized and shipped with test reports showing actual measured performance. When you're installing 40+ fiber links in a weekend data center migration, that factory certification eliminates the need for post-install OTDR testing on every link — you pull the cable, plug it in, verify link light, and move on. The SC duplex form factor is the incumbent standard in enterprise environments (as opposed to LC duplex common in high-density applications), offering tool-free latching, larger 2.5mm ferrule diameter for easier cleaning, and compatibility with legacy OM1/OM2 infrastructure during phased upgrades. The OFNR riser rating allows vertical runs in cable shafts and conduit between IDF closets without requiring plenum-rated cable, a significant cost saver in multi-story buildings where the riser path is enclosed and separated from air-handling spaces. The 3mm round cable jacket (versus 2mm zip-cord style) provides better crush resistance and pulling tension capacity during installation through conduit or cable tray, critical when you're pulling multiple assemblies in a single bundle.

OM3 fiber's 50/125µm core/cladding diameter and 2000 MHz·km effective modal bandwidth at 850nm make it the minimum acceptable spec for new 10 Gigabit Ethernet deployments — it supports the full 300-meter reach defined by IEEE 802.3ae for 10GBASE-SR, which covers 99% of intra-building horizontal and vertical distribution scenarios. For 40GbE and 100GbE applications using parallel optics (40GBASE-SR4, 100GBASE-SR10), OM3 delivers 100-meter and 70-meter reach respectively, sufficient for top-of-rack to end-of-row aggregation switch connections in most data center designs. While OM4 and OM5 fiber extend those distances to 150m and 150m, the cost delta only makes sense if your physical layout actually requires that extra reach or if you're future-proofing for 400GbE deployments. The aqua jacket color instantly distinguishes OM3 from OM1 (orange), OM2 (orange), OM4 (aqua/erika violet), and single-mode (yellow), reducing the risk of mismatched fiber types during adds/moves/changes — a particularly common failure mode in co-location facilities where multiple generations of infrastructure coexist in the same pathways.

The QuickNet system architecture uses fanout breakout designs at distribution points, allowing this 2-fiber trunk to feed SC duplex wall plates, patch panels, or equipment connections without intermediate splice enclosures. Because the assembly is pulled as a single unit with protective boots on both connector ends, there's no risk of dirt or debris contamination during the pull — the connectors stay sealed until final termination at the equipment. Panduit's factory test process validates each fiber path for insertion loss, return loss, and polarity before the assembly ships, and includes a pull-eye or pulling grip (depending on length) rated for the cable's maximum tensile load. For integrators running structured cabling projects under TIA-942-B Tier III or Tier IV data center standards, the use of factory-terminated solutions is increasingly preferred (and in some cases required) because it eliminates the variability introduced by field technician skill level and environmental conditions during termination. This assembly meets those requirements while maintaining compatibility with existing SC-based patch panel infrastructure, allowing phased upgrades without forklift replacement of entire cable plants.
